Begin to gradually add milk, stirring with a spoon until the dough begins to drain from the bowl. With a little more flour knead the dough on a floured worktop and Roll to 1.5-2 cm thick. Crop circles and Roll again, while use all the dough. We put in a tray with baking paper or greased. With a brush, remove excess flour from the rolls.
